EZEK'IEL P. PlEROE, OF CAMBRIDGE, MASSAOHUSET'Q AWNING-BLIND-HIFNGE.

SPECIFICATION forming part of Letters. Patent No. 252,895, dated January31, 1882.

Application filed April 30, 1881.

(Model) To all whom it may concern: I

Be it known that I, E. P. PIERCE, of (Jambridge, in the county ofMiddlcsex and State of Massachusetts, have invented certain new anduseful Improvements in Blind-Fixtures;

' and I do hereby declare the following to be a full and exactdescription thereof, reference being bad to theaccompanyingdrawings,forming a part of this specification, and to theletters of reference marked thereon.

With reference to the accompanying drawings, Figure 1 is an elevationot'a set of window-blinds viewed from the inside and provided with myimproved fastenings or fixtures. Fig. 2 is a similar elevation of haltthe window viewed from the outside. Fig. 3 is a perspective view, shownas an awning. Fig. 4. is an elevation of the halfblind thrown open, viewat right angles with that of Fig. 2, and a part broken out to reduce thelength of the figure. Fig. 5 is a plan of the upper hinge. Fig. 6 is asectional plan of the lower hinge-that part ofit which attaches to theblind-the tumbler beingin thelilted position thatlcaves the hook orjournal part free to pass out. Fig. 7 is a similar sectional plan,showing the tumbler dropped down,in which position it is so turned,

as shown, that thejournal cannot pass out by it. Fig. 8 is a plan of thesame part, together with thumb lever or lifter and fingcnpiece T, &c.Fig. 9 is an elevation of the tumbler with the attached cam-loop h, bywhich the thumblever H lifts it and causes it to turn on a verticalaxis: Fig. lO'is an under view of the tumbler. Fig. 11 is an elevationof a bar-fast, which secures the two parts of the blind together whenused as an awning. Fig. 12 is a plan of the same. Fig. 13 is anelevation of a keeper for the stay-rods. Fig. 14 is a plan of the same.Fig. 15 is an elevation of the lock or latch, &c. Fig. 16 is a plan ofsame.

' Like letters refer to the same or correspond. ing parts in all thefigures.

The nature of my invention relates to the iniproved construction of theseveral parts of that class of blind-fixtures which are so applied as toadapt the blind to swing. on vertical arms for ordinary use and on ahorizontal axis for awning uses, and for operating and making themsecure in the various positions contemplated in their use.

A and B indicate thetwo halvesof the blind. U is the fixed part of theupper hinge, and is provided with ajournal-sockct.

D is the swinging partof the upper hinge,

and has the vertical axisjournal a hinged or pivoted to it, with ahorizontal axis atb. Upon the head ofjournal a is formed a spur orlatch,

c, which, when the blind is closed, swings into the recess formed by theprojecting spur (Z on the stationary or fixed part 0 of the hinge. Thelower hinge has a fixed part, E, carrying ajournal, 6, also a swingingpart,f,cham-' bered and slotted. (See Figs. 6 and 7.) A tumbler, Gr,with circular head'g, is pendent upon thumb-lever H by means of acam-loop,

When the thumb-lever H is let go the tumbler falls into the positionshown in Fig. 7; but when in rehinging thelower hinge thejournal 6passes in through the slot i-it turns the tumbler in passing it into theposition shown in Fig. (i; but after passing it the tumbler falls backwith a downward-turning motion -into same position again, as shown inFig. 7. The

cam-loop h, acting on lever H as the journal.

passes in, lifts the tumbler, and when the journal has passed, thetumbler, in falling, is caused by the same cam-loop to turn back intothe position shown in Fig. 7.

The bar for securing together the two blinds (see Figs. 11 and 12) iscomposed of the guidepiece K, latch or catch L, sliding bar M, andbutton or look N. WVhen .the button N is turned up, as indicatedbydotted lines, the bar M may be moved back longitudinally from thecatch L, leaving the two halves of the blind freeto be swungopen in theordinary manner. When they are closed it is drawn forward, as shown inFig. 11, and then the buttonN being turned down, as-shown in the samefigure, it is locked.

Fig. 15 shows the shutter-fastener for securing the halves of the blindboth when swung open and when closed. 0 is a hook or-latch projectingoutside the blind, and P a similar .one projecting inside. These arefurnished IOO with a suitable catch'for each. (See Q, Fig. 15.) The partI is so jointed in connection with part 0 (like a rule-joint) that bypressing down part P part 0 is lifted and unlatched, while the socket Itis provided with a stop under part 0, which will prevent its beingpressed down so as to lift or unfasten part P from the outside, whileboth parts are free to lift for latching and unlatching, as described.

Figs. 13 and 14 show a device for holding the stay-rods when not in use.(See Fig. 1.) A cam, t, holds the rod in a. recess or hook, a. Fig. 1shows the blinds closed in the ordinary manner and fastened with thedevice of Figs. 15 and 16. The bar-fast of Figs. 11 and 12 is alsoadjusted ready to open the blind as an awning. tom of the blinds isswung out and the stayrods S hooked to the window easing (see Fig. 3)forawning use. It to be openedinthe ordinary manner, the bar-fast M isunt'astened,

asdescribed, and slid back. Then, fastenings P ()n unfastening the fastsP the botbeing lifted, each half of the blind is opened and swung back.Fast 0, catching upon catch Q upon the building, as in Fig. 15, holds itopen.

The parts may be made of any suitable material, usually, however,ofmalleable-iron castings.

I claim- 1. The tumbler h g G, in combination with socket portion f,having slot and pintle e, substantially as described.

2. The lever H,in combination with thecaniloop h, tumbler G, and theparts cf, substantially as described.

3. The pivoted and rotating journal a, coin structed with the latch c,in combination with the part (J, constructed with the projection d andpart I), substantially as described.
